Rodger,
I bought the leather seats from Ecklers last year. They matched up the very rare Cinnabar color perfectly without any material samples to go by. I bought them with the new seat foam. However...... let me suggest to NOT get the 4" bolster seat back recess, and stay with the standard 2" that you likely have on the stock seats. I don't care what they tell you. The new seat parts will fit nicely into the seat pans after you learn the correct way to take out the old ones. Be patient they will fit.
Hope this helps............. Nut
